A kind of mining double chain conveyor seal assembly, including ring seal set and stationary ring sealing shroud, dynamic Ring sealing shroud is fixed in rotating shaft, and stationary ring sealing shroud is pressed on ring seal and overlaps above, and ring seal set is with quiet The interface of ring sealing shroud smooths, and forms sealing surface.
Described ring seal set is made up of lower sealing ring, connector, adapter sleeve, fixed cover and spring, under Being provided with connector and spring between sealing ring and adapter sleeve, the bottom of connector is fixed on connection by fixed cover Set top.Lower sealing ring is formed by Ti alloy casting, and its upper surface processes through polishing, and smoothness is high, uses Life-span is long.Lower surface at lower sealing ring is provided with several for pacifying spring-loaded small sircle hole.Adapter sleeve sets There is 4-6 bolt hole, by bolt, adapter sleeve is fixed in rotating shaft, and then ring seal set is fixed on In rotating shaft, ring seal set is made to rotate along with the rotation of rotating shaft.
Described stationary ring sealing shroud is by upper sealing ring and is enclosed within the rubber sleeve outside upper sealing ring and forms, upper sealing ring Being formed by Ti alloy casting, its lower surface processes through polishing, and smoothness is high, and service life is long;Rubber sleeve Lateral surface is provided with external screw thread, it is simple to fixing upper sealing ring.
Described spring is provided with several, equidistant is arranged between lower sealing ring and adapter sleeve, and balancing force is big, Can make that the sealing surface between upper sealing ring with lower sealing ring is combined is more tight, when self-aligning bearing is beated, It is not result between sealing surface occurring gap, it is therefore prevented that the generation of oil leakage phenomenon.
The beneficial effects of the utility model are: upper sealing ring and lower seal are formed by Ti alloy casting, table on it Face processes through polishing, and smoothness is high, and ring good airproof performance, service life is long.Lower sealing ring and adapter sleeve it Between be provided with several spring, balancing force is big, and the sealing surface between upper sealing ring with lower sealing ring can be made to be combined more Add closely, it is therefore prevented that the generation of oil leakage phenomenon.
Accompanying drawing illustrates:
Fig. 1 is structural representation of the present utility model.
Fig. 2 is sectional structure schematic diagram of the present utility model.
In figure: 1 ring seal set, 11 lower sealing rings, 12 connectors, 13 adapter sleeves, 14 fixed covers, 15 Spring, 2 stationary ring sealing shrouds, 21 upper sealing rings, 22 rubber sleeves.
